I just recently replaced my heater core which did solve the heat problem...but the heat is still not blowing out as hot as i think it should be. It feels warm but isn't even enough for the car to heat up. When i bought the jeep it had no heat so im not sure if something else might be wrong with it or if maybe thats just as warm as the heat gets..Any ideas? It feels like its blowing out about 50-60 degrees..

The engine is at operating temp. If anything it might be running a lil to hot. My uncle who is a mechanic told me it is probably the thermostat, which is kind of what i thought it might be but didnt wanna waste the time and money to replace.

My Wrangler 4-banger runs really cold blooded. Even in hot weather; it barely gets to 210 degrees. Try a changing the thermostat for a hotter one. Also, in really cold weather, I block off about 2/3 of the radiator with a piece of cardboard, which bring the coolant gauge up to about 1/2 way and gives me some decent heat. Hey, it's a Jeep. If you want too much comfort, you should be driving a Toyota.

Well I took my a/c therm. with me this morning to see what the air in my 87 4.2 came out of the defrost at and with my engine temp at 180-190 the air stayed at 70-72 at the defrost vents. the outside temp this morning was 22 and light snow.
and it makes my soft top comfortable but not hot ..lol
it warmed up to 45 today and the vent air was still at 72 and i had to turn it off it was so hot in my jeep. just thought maybe this info might help you some how
